GAS-LAMP.

gas lamps.

The objects of this invention are, first, 4to provide an improved gas lamp having inverted burners in which the parts of the lamp above the burner are protected so as not to be undulyheated by the burners, and one in which the gas is not unduly heated before reaching the burner tips. Second, to provide an improved gas lamp having anv inverted burner, in which the heat of the gas is not conducted away from the burner, but is4 largely utilized'in heating the mantle. Third, to provide an im roved inverted burner for gas lamps, by w lch the fluctuation of the flame about the burner tipis largely overcome.

.Further objects, and objects relating to will definitely appear from the detailed description to follow. I accomplish the objects of my invention and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accomanying drawing forming a part of this specication, in which,

Figure 1 is a vertical section of a structure embodying the features of my invention, portions being shown in full lines to better illustrate their form. Fig. 2 'is an enlargedv vertical section taken on a line corresponding of Fig. l looking in the direction arrows at the ends of the section Fig. 3 is a erspective view of the the burner tube. lsimilar letters of reference t0 line 2-2 of the little In the drawing,

refer to'similar parts throughout the several views.

- Referring to the drawing, in the structure illustrated, the burners are grouped about. a central chimney A having an outwardly ro- A at itslower end. he flange A is provided with a down-turned rim 215".u his general that shown in my two Vapplications for Letters Patent iled concurrently herewith.

pieces.

'strict or reduce the structure illustrated, the burners are connected to the .gas delivery ring B which is connected to the gas supply pipe B.

The burners are L preferably suspended from the ni ples C infth'e gas delivery ring, the nipples eing inside thereof, as illustrated. The burner tube F is preferably connected to the nipple C by the coupling section l), which is threaded upon the nip le vand is also threaded to receive the tube lip as clearly appears in Figs. 2 and 3. The tube section D is pro'vided with large openings d may be inserted and An ianipulated for arranging the same upon the nipple-C. 'Ihe nipple C is shouldered and threaded to J'receive this nozzle independently of the burner tube, so that it may be removed or put in po'- sition without inany wise disturbing the remaining partsof the Liiner.

preferably arranged on the through which the nozzle C A needle valve cis provided for regulating l Y the dischargeA of the preferably illustrated.

A. sleeve-like valve E is threaded upon the tube section D and adapted to be -adjusted nozzle, the valve c being threaded through the nipple as is over the openings. d to regulate the air and to i permit the full opening of these openings to allowthe manipulation of the nozzle. vThe tube section F is arranged through the-flange A of the chimney and is provided with a tapered portionf, which, serted through the o flange, effectively sea he burner ti burner tube so t adjusted as desired. Also, it is a convenience in manufacturing to form the parts in The 4burner tip gradually tapers downwardly, and is provided with an inverted-flange f at its mouth arranged to rethe deliveryopening thereof. `It is found in. practice that l of inverted burners is for the flame to fluctuate and be unsteady, due to the tendency ening ofthe plate or s the opening. Y

the tendency IOO of the llame to 'creep back into the burner.

By restricting or reducing the delivery opening of the burner, as I have illustrated, this tendency is largely overcome. vIt is found in'practice that the heats the partsof the lamp above, and not only makes it very diffcult, vnot im ossible, to adjust and manipulate the va ves and other parts when the lamp is burning, but greatly detracts from the candle powerv ofthe lamp, 'by what I believe to be a breakheat from the yburners IIO ing down or chemical disintegration of the gas, also 1preventing the proper adiniXture of air wit r the gas and causing the deposit of carbon on the mantle and burner and adjacent parts of the' lamp. This is particularly true where a group or cluster of burners is provided. All this is effectively overcome by .arranging the burner tube through the wall of the chimney, with the burner tip below and valves outside of the chimney, and by forming the tube F of a material which is a nonconluctor of heat, such as magnesia, lavite,Y or some equivalent nonconducting material. The burner tip F is also preferably formed of magnesia or similar nonconducting material, as it does" not become coated with carbon, or if it should become coated, the carbon burns o fl` therefrom. By forming the tube F of a material which is a nonconductor of` heat, the heat is not conducted away from the burner ti to the other parts of the lamp, and in ad( ition to this, the heat is kept at the burner tip where it is effective for heating the mantle.

By arranging the burners through the wall ofthe chimney, the heated gases are carried away from the parts of the lamp which it is desired to protect. The plate or defletor through which the burner tube is arranged need not of necessity be in the form of a flange on a chimney as I have illustrated., although I prefer it in that form and relation.

While my improved burner is-particularly designed'and adapted for use in connection with my improved construction of the lamp illustrated, it is evident that it is of advantage for use in other relations.

I. have illustrated and described my imroved structure in detail in the form preerred by me on account of the structural simplicity and convenience` in manipulating. I am aware, however, that it is capable of considerable variation in structural detail without departing from my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
